Bilevel large neighborhood search for the electric autonomous dial-a-ride problem

open access: yesTransportation Research Interdisciplinary Perspectives, 2023
The electric autonomous dial-a-ride problem (E-ADARP) represents a challenging and practically relevant extension of the dial-a-ride problem, which takes electric vehicle charging into account. It introduces battery constraints and the option to recharge

The Electric Dial-a-Ride Problem on a Fixed Circuit

open access: yesTransportation Science, 2023
Shared mobility services involving electric autonomous shuttles have increasingly been implemented in recent years. Because of various restrictions, these services are currently offered on fixed circuits and operated with fixed schedules. This study introduces a service variant with flexible stopping patterns and schedules.

Solving the dial-a-ride problem using agent-based simulation

open access: yesSouth African Journal of Industrial Engineering, 2016
The ‘dial-a-ride problem’ (DARP) requires a set of customers to be transported by a limited fleet of vehicles between unique origins and destinations under several service constraints, including within defined time windows.

The Clustered Dial-a-Ride Problem

open access: yesProceedings of the International Conference on Automated Planning and Scheduling, 2019
We study a variant of the classical dial-a-ride problem, with an application to public transport planning in rural areas. In the classical dial-a-ride problem, n users each specify a pickup and a delivery location, and the aim is to plan the least cost route to cater all requests.

Long-Distance Directional Dial-a-Ride Problems

open access: yesProceedings of the 9th International Conference on Vehicle Technology and Intelligent Transport Systems, 2023
We consider vehicle routing problems that occur in practice in the context of long-distance ride-sharing. On the one hand, the instances of our problems share the helpful property that the passengers travel in roughly the same geographical direction. On the other, the required cost function has ordering-dependent components.
